BATH-TUB-HEATING DEVICE.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed September 4, 1906. Serial No. 333,196.

To all whom it may concern:

Be it known that I, THOMAS B. JARVIES, a

citizen of the United States, residing at Kan- 1- tube.

sas City, in the county of J aciason and State of Missouri, have invented certain new and useful Improvements in Bath-Tub-Heating Devices, of which the following is a specification.

My invention relates to improvements in bath tub heating devices.

upper end of the tubular burner support, the mixing chamber and one end of the burner Fig. 5 is a cross section taken on the dotted line a t of Fig. 4.

Similar characters of reference denote similar parts.

1- denotes the ordinary bath tub of rectangular form.

2 denotes the water faucet disposed adjacent one end of the tub 1 for admitting cold The object of my invention is to provide a Water to the tub. Disposed lengthwise unnovel water heating device for bath tubs by which the greater amount of heat is applied to the bath tub adjacent the place where the cold water enters the tub. By the use of the heating device of my invention, the water is thoroughly heated while it is entering the tub, while that portion of the tub distant from where the water enters and which sup ports the bather is not heated sufliciently to burn or be uncomfortably hot to the person of the bather.

To accomplish the object of my invention, the burner for heating the tub is provided with means by which it applies the greatest amount of heat to the portion of the bath tub adjacent where the water enters the tub, the heat applied decreasing in amount toward the distant portion of the tub.

My invention provides a heating device comprising a burner disposed lengthwise under the bath tub, the opposite ends of the burner being independently adjustable toward and from the tub.

My invention provides further a longitudinal burner disposed under the bath tub and having a longitudinal row of holes which are disposed from one end to the other at increasing distances apart, whereby the greatest amount of heat may be applied at one end of the tub adjacent which the cold water enters the tub.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings I have illustrated my invention.

Figure 1 is a longitudinal vertical central sectional view of a bath tub provided with my heating device. Fig. 2 is atop view of a portion of the heating mechanism, in which the discharge openings of the burner are disposed at increasing distances apart. Fig. 3 is a top view of the mechanism shown in Fig. 2, the burner tube having the discharge openings disposed at equal distances apart. Fig. 4 is an enlarged vertical sectional view of the der the tub 1 is a horizontal burner tube 3 having on its upper side a longitudinal row of discharge openings 4. In the tube illustrated in Fig. 2, the openings 1 are disposed at increasing distances apart, those being closer together under that portion of the tub 1 adjacent which the water enters through the faucet 2. The greatest amount of heat will thus be applied to the portion of the tub adjacent where the water enters, thus heating the incoming water and not heating the opposite end of the tub so hot as to be uncomfortable to a person sitting on the bottom of the tub at said opposite end.

5 and 6 denote two vertical members externally screw threaded and fitted respectively in threaded holes provided. in two horizontal plates 7 and 8 respectively adapted to rest upon the floor 9. The upper end of the member 5 has mounted on it a hollow fitting 10 provided with a horizontal tubular projection 11 which extends into an opening provided in one end of a mixing chamber 12, said mixing chamber having an opening in its other end in which is mounted one end of the tube 3, on the other end of which is mounted. one end of an elbow 13, the lower end of which is secured to the upper end of the member- 6. The fitting 10 is provided at the side opposite the projection 11 with a horizontal externally screw threaded projection 14c provided with a screw threaded longitudinal hole in which is fitted the threaded stem 15 of a valve, the inner end of which stem is adapted when the stem is properly turned to close the opening in the projection 11. On the opposite end of the stem 15 is secured a hand wheel 16 by which the stem is turned. On the projection 14 is mounted a packing box 17 threaded at one end to fit the threaded projection 14, the other end of the box having a central hole through which the stem 15 extends.

18 denotes packing material intermediate the outer end of the projection 14 and the outer end of the packing box 17 and encircling the stem 15.

19 denote air inlet holes in the mixingently vertically adjusted to the positions desired.

By properly adjusting the'plates 7 and S, the burner tube 3 may be made to incline downward toward the elbow 13 thus disposing the burner tube 3 with the end adjacent the portion of the tube which first receives the cold water nearer the tub than the opposite end of the burner, in which position the tub adjacent where the water enters will be heated to a greater degree than the opposite end of the tub.

The operation of my invention will be apparent. By turning the hand wheel 16 in the proper direction the passage in the projection 11 will be opened and the fluid fuel will pass from the tubular member 5 into the fitting 10, thence through the tubular projection. 1 1 into the mixing chamber 12, where the fuel is mixed with air, the mixture passing thence into the burner tube 3 and out through the openings 4 after which it is ignited and heats the underside of the tub in the manner hereinbefore described. If at the same time the faucet 2 is operated to discharge the water into the tub, the gaseous mixture from the burner is ignited, the wa ter will be heated as it enters the tub.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is 1* 1. The combination with a bath tub, of means for introducing water into the tub adjacent one end thereof, and a burner disposed longitudinally under the tub and having a series of discharge openings disposed at increasing distances apart along the length of the burner, the openings being closer together adjacent the end of the tub in which the water enters.

2. The combination with a bath tub, of

means for introducing water into the tub adjacent one end thereof, and a burner disposed lengthwise of the tub and having its ends independently adjustable toward and from the tub, the burner having a series of discharge openings disposed along its length at increasing distances apart, the openings adjacent where the water enters the tub being closer together than at the other end of the burner.

3. The combination with a bath tub, of means for introducing the water into the tub adjacent one end thereof, a burner tube disposed longitudinally under the bath tub and having a longitudinal row of discharge openings disposed apart at distances increasing from one end of the tube to the other, and means for varying the distance of the burner tube relative to the tub.

4. The combination with the bath tub, of means for introducing water into the tub adjacent one end thereof, a burner tube disposed longitudinally under the tub and having holes for discharging the fluid against the tub, supports for the burner tube vertically adjustable toward and from the tub, one of the supports being tubular and conveying the gas used in the burner, an air mixing chamber connected to the said tubular support and to said burner tube and having air inlet openings, and a valve controlling the passage of gas from the tubular support to said mixing chamber.

5. The combination with a bath tub, of means for introducing water into the tub adjacent one end thereof, a-burner disposed lengthwise under said tub, two vertical externally screw threaded members for sup porting said burner at opposite ends respectively, one member being tubular and discharging into said burner the gas used, and two plates adapted to be supported on the floor and having screw threaded holes in which said two members are respectively fitted.

In testimony whereof I my signature in presence of two witnesses.
